Answer:
x = 44/19, y = 33/20
Step-by-step explanation:
Multiply the first eq by 18, to get:
90/y - 36/x = 39
so 36/x = 90/y - 39
in this form we can plug it into the second eq:
90/y - 39 - 24/y = 1 =>
66/y = 40 =>
y = 66/40 = 33/20
Fill that in the first:
100/33 - 2/x = 13/6 =>
200/66 - 143/66 = 2/x =>
57/66 = 2/x =>
57x = 2*66
x = 132/57 = 44/19
16/8 which is equal to 2/1 which is equal to 2
The slope is 2
Answer:
(1, 8)
Step-by-step explanation:
Answer:
x = -1/10 or -0.1
Step-by-step explanation:
-1.8 - 6x = 6(0.1 + 3x)
-1.8 - 6x = 0.6 + 18x
-6x - 18x = 0.6 + 1.8
-24x = 2.4
-x = 2.4/24
-x = 24/10 / 24
-x = 24/10 * 1/24
-x = 24/240
-x = 1/10
x = -0.1
